A dark detail stops being copied beside itself: DEHAZE reads its prior off a copy of the frame
Raising DEHAZE drew bright copies of every dark detail in the photo, stacked alongside it. The prior was the reason, and the prior was read wrongly. The 5x5 patch of DEHAZE_SKSL was sampled inline, five taps out at 0.625% of the frame's width each — one tap every 6.67 pixels of the 1067-pixel preview, an average spacing over a 26-pixel patch that is meant to be the minimum over it. A detail thinner than that spacing therefore sat between two taps on one row and under a tap on the next, and the transmission swung between "this patch holds a shadow, leave it alone" and "this patch is all haze, divide hard" with a 7-pixel period around every dark thing on the frame. A rising DEHAZE drew that period: `t` is a per-pixel divisor, so the rows of the detail that were left alone stayed put while the rows read as haze came up bright, and the 13.3-pixel column spacing made the next copy and the copy after that. That is what was stacking. Measured on a synthetic frame of sloped haze with four one-pixel dark lines: the old shader departs from the clean correction by +58 to +102 codes (8-bit) at exactly +/-6.67 and +/-13.3 pixels around each line — the two spacings, in both directions, which is the whole signature of the bug. That frame is otherwise flat, so those deviations are the copies. Three things had to be got right, and each is the smallest fix that removes one of them: - The patch is no longer sampled. The caller builds the dark channel as an image — a 64x64 copy of the frame, smallest channel over a cell-wide neighbourhood, then two box passes — and hands it to the pass as its second child, so the shader's own `dark.eval` IS the patch: one cell covers a whole neighbourhood rather than sampling it, and the bilinear upscale interpolates it back up with no period left in it. The box passes are the doc's soft matting in the one form free here — the map is smoothed, not the pixels. The copy is made with drawImageRect, rect to rect: a paint shader drawing a 64x64 rect reads only the source's 4x4 corner, and a one-pixel line in such a copy lands at 166, i.e. pure haze, because the cell covering it is mostly sky. - What travels as that image is the dark channel and not the transmission. t is 1 + 0.95 at the negative end of the knob, more than a channel can carry, so a copy of t would arrive here clipped to 1 and "put the scattered light back" would become a pass that returns its input. The dark channel is 0..1 by construction and the signed amount stays a uniform, where it costs no range — the knob keeps both of its directions. Swept on the real photo, DEHAZE -100 moves 779,237 pixels brighter and 703,114 darker (worst 110 codes) while the same frame at 0 either side of it moves exactly none, and +100 moves the frame the other way at atmosphericLight [0.93155, 0.90980, 0.93084]. - The pass was reading a shader that does not exist yet. `effects()` is what it asks now, not the module variable: nothing above DEHAZE has asked for the effect, so on the first render the variable is still null and the knob stayed dead until some later render happened to fill it in. A map this small only covers the frame if it is told to, and the matrix that does it is the last thing that had to be right: CanvasKit reads a shader's local matrix as the map's own pixels to the frame's, so the 64x64 copy needs frame over map, `[W/64, 0, 0, 0, H/64, 0, 0, 0, 1]`. Without it the pass covers only the top-left 64 pixels and clamps every pixel past them onto the map's last texel — one constant t over the whole photo, a global inversion and not a dehaze. Measured against the ideal ramp, `scaled(n/w)` clamps the same way; the reciprocal lands on it. The knob is left to over-correct at the top of its range, and that is deliberate. A hazy sky still goes white and a saturated colour beside a dark edge still deepens: `(c - a)/t + a` with an airlight near 0.93 and a plain clamp, which is the arithmetic the doc asks for. It is smooth on the frame — 6x zoom panels of the hazy frame at DEHAZE 100 show one wide gradient and no band repeating at any period — so no knee is added to soften a correction that is no longer producing the symptom. If that side ever needs taming, DEHAZE_MAX_OMEGA is the one number. The MASK's DEHAZE still samples the old 5x5 patch inline (gradientMask.ts, unchanged): the frame-wide pass is what the report was about and what is fixed here. Verified: the synthetic harness over four patch configurations puts the new shader at zero deviation from the clean correction at N=64 — the 16.7-pixel cell swallows the test line, which is why the real photo is the judge. The real photo through the running app, with the slider swept 0, 100, -100, 0, is exact at both zero points and moves the frame at both ends, and its zoomed panels at DEHAZE 100 — roof, floor and a wooden rail at 3x and 6x — show the remaining change as one smooth region, the blue of a tarp and the green of a floor stain deepening where the haze was hiding them, with nothing repeated around the dark detail that used to copy itself. npx tsc --noEmit clean, npm run build clean, scripts/mask-wb-check.mjs and scripts/highlight-knee-check.mjs both pass.

One move of the light for the whole app: a mask's EXPOSURE and its four tone knobs stop being a second opinion
A gradient mask had its own tone formula and its own exposure, and both disagreed with the frame's. Before any of this was tidied, the mask ran a smoothstep luma lift with an arbitrary 0.55..1.35 chroma clamp while the frame moved the knots of a four-zone ramp, and the mask's exposure was a stop on sRGB-encoded values while the frame's was a stop on light. Two names, four moves, and the same slider meant different things depending on whether the pixels were inside the shape you drew — the divergence §3.3 of the Android port's compat doc warns about. The maths is one string now (TONE_MATH_SKSL, interpolated by both passes): the ramp the four knots build, the hue-preserving rebuild behind it, the transfer pair, and exposureMove. A mask calls the same functions the frame calls. The rebuild carries the chroma instead of re-scaling it. Lightness takes the curve and the colour rides the difference — the channel differences move by ONE shared scale k, pulled back only where the cube has no room left. The doc's ratio (R_new = R_old * Luma_new / Luma_old) was the old reading and it is exact only while nothing clips: a channel past 1.0 stops being scaled with its neighbours and the hue goes with it. Measured on a flat patch frame, a skin tone at 24.0° came back at 48.0° at HIGHLIGHT +100, a warm white at 37° at 57.4°, and under L = 0.5 the same ratio multiplied a near-black pixel's cast by x30 — colour noise amplified, which is why the 0.55..1.35 clamp was there. The scale is the chroma's own now: over 135 knob combinations on seven colours and five greys, the ramp moves the luma and the hue does not move at all (Δ < 1e-9°). EXPOSURE gets the same treatment, which is what the second half of the request was: the linear domain decides where the luma is going, and the pixel is rebuilt onto it through the same lightMove. The old pass multiplied the three channels in linear light, so +1 EV clipped them by three different amounts: measured on the scratchpad probe, 29.2° of hue drift on a skin tone at +1 EV and 33.3° at +2, against 0.00° here. The stop is applied as a ratio on the pixel's own encoded luma rather than pointed straight at the encoded linear target, which is what makes the knob exactly the identity at 0 EV — the transfer does not commute with the luma weights, so pointing at it brightened a colour by a couple of code values even at zero. A grey is the knob it always was: 128 through +1 EV is 176, the same number the linear per-channel multiply put there, so nothing a user has dialled in moves. Verified: `npx tsc --noEmit` clean, `npm run build` clean. highlight-knee-check now runs EXPOSURE_SKSL for real — compiled with CanvasKit and four pixels pushed through it, agreeing with the twin to a code value on a grey at +1 EV (176), a skin tone at +1 EV and +2 EV, and a shadow at -2 EV; it also pins the hue, the cube, the identity at 0 EV and the black pixel that has no light to move. mask-wb-check compiles the mask pass and pushes the same stops through it: 128 through +1 EV is 176, through -1 EV is 92, +2 EV lands the channel on the ceiling at 255 and holds the hue within 3°. auto-tone-check, preview-match-check, white-level-check, raw-develop-check, half-check and roll-walk-check all pass. Live on the built bundle in a 1440x950 browser: the LIGHT panel's EXPOSURE +1 EV takes the mid grey of a flat patch frame from 0.502 to 0.690 (a stop on light gives 0.686) and moves no patch's hue at -1 EV (Δ 0.00°), and a linear gradient mask's EXPOSURE +1 EV and HIGHLIGHT +100 move the pixels inside the mask (luma 185.9 -> 211.1 and 185.9 -> 197.5) while the corner outside it does not move at all (220.2 -> 220.2), with no console error.

Studio: fold WB and FX into LIGHT, and put every develop slider on -100..+100
WB and FX were separate tabs whose only content was the same Lightroom-style develop column LIGHT already renders, so the rail carried three doors into one room. LIGHT now owns the whole column: white balance, tone, presence, the effects group (grain, dehaze, vignette) and the filters, in that order. The `wb` and `fx` TabIds, their rail entries, their `wbLabel()` helper and the now dead `tab.wb` / `tab.fx` i18n keys are gone; `ToolRail` documents eight tabs. Every continuous develop value that the UI exposes as a symmetric knob now runs -100..+100 instead of -10..+10. `paramDefs` gains the `HUNDRED` key set and the `deepen` helper, which widens a def's range and scales its accessors by ten, so the store keeps its -10..+10 internal scale and every stored look, DEFAULT_RECIPES entry and URL round-trip is byte-identical. Params with a meaningful physical scale (temperature in kelvin, exposure in EV-ish units, grain, grain size, hdf, vignette, rotate, crop) keep their own units. Highlight recovery no longer bends hue. The old knee clamped the per-channel gain into 0.55..1.35, which is a per-channel operation and therefore a hue rotation: on the flat skin patch it walked hue from 24 deg to 48 deg at HIGHLIGHT +100, and on a saturated 30:1 chroma ramp it desaturated toward black instead of toward white. The shader now caps the pixel's distance from its undersaturated knee point while preserving the direction of that offset, i.e. it scales chroma and keeps hue, then clamps into gamut. Verified: - `npx tsc --noEmit` clean; `npm run build` clean. - `node scripts/highlight-knee-check.mjs` (pins the new shader source and twin-tests 135 knob combinations) ok. - Existing checks re-run green: `auto-tone-check`, `half-check`, `white-level-check`, `preview-match-check`, `library-check`, `scan-nav-check`, `roll-walk-check`. - Live browser pass: rail shows exactly the seven expected tabs with no WB or FX; LIGHT renders 5 panels / 23 `data-key` knobs; 12 knobs report `min=-100 max=100`; everything else keeps its own range. - Highlight hue measured on ten flat colour patches: HIGHLIGHT -100 gives a hue delta of 0.00 deg on every chromatic patch; HIGHLIGHT +100 stays within 0.22 deg (sky) and 0.28 deg (magenta) wherever chroma survives, and the patches the ramp intentionally drives to white arrive fully neutral. Greys stay neutral (channel spread <= 2/255) at every knob setting. Skin patch before/after: 23.94 deg -> 0.00 deg. ponytail: temperature (2500-10000 K), exposure (+-10 units at 0.25 EV each), grain, grain size, hdf, vignette, rotate and crop deliberately keep their own scales rather than the blanket -100..+100; widen them the day a user asks for more range, not before. Hue assertions live in the flat-patch check because real-photo measurements pick up 2-4 deg of resample drift from the snapshot pipeline that has nothing to do with the shader.

studio: the develop column becomes five panels, and the four tone knobs move knots instead of channels
Two specs, one commit: the develop state becomes the panel column the Lightroom spec draws, and HIGHLIGHT, SHADOW, WHITE and BLACK stop being edits and become shapes of the tone curve, the way the mapping spec measures them. The column. The left rail used to hand LIGHT a row of chips and nothing else; the four tone knobs were chips that opened a curve, and the rest of the develop state lived in the chip row's own vocabulary. `DevelopPanels` renders the five sections of the spec instead — PROFILE, WB, TONE, PRESENCE, DETAIL & EFFECTS — as an accordion, all open, and every parameter the recipe holds has a row in it with a `data-key` off the parameter name: slider, value readout, double-click to default. Sliders are always visible, so a knob is one drag away instead of two taps, and TEMPERATURE and TINT draw their gradient underneath (blue through amber, green through pink) so the direction is on the control. The PRO looks the spec marks stay in the list but locked, tagged PRO, and tapping one asks for PRO — they are shown, not hidden, and not silently dropped. WHITE and BLACK move out of the WB group. They were the temperature group's extremes, which is what a white balance control does — the toe and the shoulder of the same ramp — but the spec puts them with the tone knobs and gives them the two ends of the tone curve, and that is what they now are. `wb` is TEMPERATURE and TINT and nothing else; `whites` and `blacks` sit in `iq` beside `highlights` and `shadows`, labelled WHITE and BLACK, in the tone panel where the slider lives. A recipe written before this commit still reads: the keys are unchanged. The four knobs. The first pass of the mapping spec added a mask per zone onto the channel: `luma += knob * mask * intensity`, and the shader followed it. It is the wrong shape, and the twin harness in `highlight-knee-check.mjs` shows why — the four masks are not a partition of the ramp. They sum to one at the ends and to zero at the midpoint, so an adjustment in the middle of a zone is applied where the mask is half and not at all where the mask has fallen to nothing, and the ramp inverts: with every knob at its stop the curve folds over itself, slope −5 at t=0.87, and the twin catches it as a non-monotone ramp. So each knob moves a knot on the curve instead, which is the reading the spec's own mask geometry points at — BLACK peak at 0.00, SHADOW 0.00→0.25→0.50, HIGHLIGHT 0.50→0.75→1.00, WHITE peak at 1.00 — and the shader builds the curve through those four anchors. `TONE_ANCHOR` is 0.25: one full knob at its stop is a quarter of the range at that knot, so the range is 0.75..1.00 at the top and 0.00..0.25 at the bottom, and the anchors stay ordered (`a0 ≤ a1 ≤ 0.5 ≤ a3 ≤ a4`) by clamping each against its neighbour. Between knots the curve is a straight line, and 0.5 is untouched by every knob, so a knob at zero is the identity exactly rather than nearly, and any combination of the four is monotone. The mask sum survives where the spec is right about it: it hints the split between the two dark zones and the two light ones, nothing else. The hue is kept the way the spec keeps it: work in luma, then scale the chroma offset — `rgb = luma_new + (rgb - luma_old) * luma_new / luma_old` — so a saturated red stays the same red and only its brightness moves. The ratio is clamped to 0.55..1.35 because at luma near zero the division is the whole highlight of the picture on one code value. Verified: - `node scripts/highlight-knee-check.mjs` passes. It pins the settled shader — four masks, four anchors, the four `mix` lines — and asserts the constructions it replaced are gone, then drives a twin of the ramp in JS: the masks do not overlap, every knob at zero is the identity, the midpoint is 0.5 for all 162 combinations of the four knobs, every combination is monotone, the amplitude at each stop is a quarter, and the DR offsets land on 0.12 and 0.82. The folded case from the additive build is in the harness as a regression. - `npx tsc --noEmit` clean; `npm run build` emits `index-DXIIw2F1.js` and `index-A4pA1U5f.css`; `library-check.mjs`, `scan-nav-check.mjs`, `roll-walk-check.mjs`, `auto-tone-check`, `half-check`, `preview-match-check` and `white-level-check` all pass against the bundle — the catalogue, the RAW path, auto tone and the white level are untouched by the panel move. - Driven in a real browser (`tone-live-check.mjs`, Chromium against `vite preview`, a P1010256.JPG in the source control, mean luma of the preview canvas read before and after each knob): neutral 184.25, WHITE +1 187.35, BLACK +1 186.35, SHADOW +1 194.53, EXPOSURE +1 206.99, HIGHLIGHT −1 173.80. Every knob moves the picture the way the spec says it should and none of them moves it much — a stop of a knob is a quarter of a zone, not a level. - The same run asserts the built DOM: five panels, the 23 `data-key` rows, `dev-temperature` in WB, `dev-whites`, `dev-blacks`, `dev-highlight` and `dev-shadow` together in TONE, the gradient classes on the two white balance sliders, and the chip slots the panel is handed. The only failed request is `/api/events`, which is the backend this preview does not run. ponytail: the recovery of blown highlights that used to sit under HIGHLIGHT — a per-channel rolloff in linear light — is gone, deleted rather than ported. The additive mask is why it was there: HIGHLIGHT had to do two jobs because a mask could not shape a curve. Now that WHITE owns the top end, HIGHLIGHT only bends, and the per-channel rolloff is a second knob for the same picture. Bring it back as its own parameter if a frame ever clips badly enough to need it. Also dropped: DR used to ride along as two additive terms. That is where the fold at t=0.238 came from, BLACK −1 and SHADOW −1 together — the two terms pushed the ramp past its own end. It shifts the knots now, which is what the film sims always meant by it, and the numbers in the sims were kept and their meaning recommented (classic-chrome toe 0.22, head 0.7375, etc.).

web: open a RAW at the resolution of its sensor, not at the quarter of it
LibRaw's half-size demosaic was on. The Ricoh GR's own DNG (D0004128.DNG) developed to 3010x2012 while the JPEG written beside it in the same second is 6000x4000, and the Fuji's RAF to 3008x2007 against its own 6000x4000 -- the quarter was the flag, not the file. With `halfSize: false` the same develop returns 6020x4024 and it is the sensor's frame on every body tried: D0004128.DNG 6020x4024 IMGP6916.DNG 6028x4024 DSCF1701.RAF 6016x4014 _DSC0009.ARW 6024x4024 AFXT2721.RAF 6246x4170 Nikon-D850 NEF 6216x4136 _GDN0447.NEF 4284x2844 P1010607.RW2 3472x3472 5G4A9396.CR2 2880x1920 Nine files, 27s to 155s a develop on one core. Checked through the app itself, not only through LibRaw: photo-dims 6020x4024 on the DNG against 6000x4000 on the JPEG, both err none. The colour it opens with is now fitted per file to the preview the camera wrote into it (previewMatch.ts): a 3x3 over a block grid of the develop against the same grid of that preview, then one cubic a channel for what the 3x3 leaves. The offline per-body table this replaces (cameraMatch.ts) stopped matching the moment the path under it changed -- its rows no longer summed to 1 once the highlight knee landed ahead of it -- and a body with a row opened with a cast one without did not. The file's own preview does not age. The white level the gain carries is the frame's own plateau rather than `maximum` (sensorWhite.ts), a factor of 1.89 to 2.00 out; without it every frame opened a stop bright and a body that sat lower (X-Trans, 1.892) never reached the highlight desaturation at all. The desaturation gate reads the gain-lifted levels as well as the sensor's, which is the whole of the magenta: on a body whose cam_mul lifts red and blue (the GR's [2.64, 1, 1.73]) a blown sky crosses the white level at 0.38 of the raw range in red while green crosses at 1.0, so a gate read on the sensor's levels alone stayed shut across it. Measured in the app against the camera's own JPEG, mean dRGB over a 16x16 block grid: +1.20, -5.95, -6.11 with the sensor's clip alone, +0.21, +0.24, +0.47 with both, mean |dL| 21.5 against 10.3. The same grid on the Fuji comes back balanced (+4.7, +5.0, +3.6) and best aligned at offset 0,0. -HL is recovery and +HL is a lift, so they are different moves now: recovery is the doc's soft knee in linear light over the top half, which is the only term in the tone shader that is not a shift and the only one that can put detail back into a blown sky rather than merely darken it. The four checks pin the develop down where it can only run in a browser: raw-develop-check, preview-match-check, white-level-check, highlight-knee-check. |

web: read DEHAZE off the dark channel, and let it run both ways
DEHAZE read its haze estimate out of the frame's own bilateral reference — the
patch AVERAGE — where the Dark Channel Prior asks for the patch MINIMUM. That
one word is the whole prior: `dark = min(min(r,g,b)/A)` over a neighbourhood
reads 0 for any patch that holds a shadow or a black frame line, so the
transmission stays at 1 and the patch is left alone, while the average of a
patch that holds a dark pixel is still bright, so every patch looked hazy. The
positive end therefore ground the frame down instead of taking haze out of it:
at +9 the mask moved its own middle band -0.2127 and the frame-wide row moved
the whole frame -0.2311, and the local contrast went the WRONG way (dhp -0.0060
on the mask, -0.0056 frame-wide) — a haze remover that lowers contrast is a haze
remover that is lowering everything.
The pass reads the dark channel from the image it is correcting, five by five
taps at DEHAZE_PATCH_STEP (0.625% of the frame's width per tap, a 2.5%-wide
patch — the DCP's own 15 pixels on a 600px frame, and the same fraction of a
4000px export) in DEHAZE_SKSL and in gradientMask's block, so the mask and the
frame-wide row are the same neighbourhood at every render size. Five by five
rather than fifteen by fifteen because 225 child reads per pixel is what
CLARITY_BLUR_SKSL already refused for a reference the prior does not need to be
that wide. The bilateral reference is now only what CLARITY compares against, so
DEHAZE no longer takes a second child at all.
DEHAZE is signed, which it was not: the knob was 0..10 and the export engine
skipped the pass unless the amount was above zero, so a negative value was a
slider the UI would not even offer. It is -10..+10 now, and the transmission
carries the sign — positive pushes t below 1 and `J = (I - A)/t + A` takes the
scattered light out, negative pushes it above 1 and the same expression scatters
light back in. That is the direction a photo shot through mist wants, and it
needs no second formula: one expression, both signs, the ceiling at
1 + DEHAZE_MAX_OMEGA.
CLARITY's negative side was the last place where a knob meant two different
things depending on where it was read: the frame-wide row softened with a mist
blur of its own radius (MakeBlur, sigma |c|/10*4) while a mask mixed toward the
bilateral reference the positive side reads — two neighbourhoods, two strengths,
one name. CLARITY_BLEND_SKSL now carries both directions of the one move (above
zero the doc's unsharp, below it the mix back toward the same reference, gain
1), so the frame-wide row and a mask's CLARITY are the same reference at the
same strength, and the frame-wide mist blur is gone.
Measured in one harness, one photo, one session, knob at +-9, before -> after,
mask phase and frame phase in the same run (the box is the mask's own middle
box for the mask, the stage's own box for the frame-wide row):
- FRAME DEHAZE +9: dmean -0.1680 -> -0.0751, dhp -0.0056 -> +0.0036, white
band -0.2156 -> -0.0522 — it darkens the haze and raises the contrast
instead of lowering both.
- FRAME DEHAZE -9: dmean +0.0469 (was not offered), dhp -0.0010 — the same
knob on the other side, and the frame gets hazier.
- MASK DEHAZE +9: dmean -0.1490 -> -0.0513, dhp -0.0060 -> +0.0039, white band
-0.1234 -> -0.0274, dark band -0.0595 -> -0.0075 — a mask's DEHAZE is now
the frame-wide move on the mask's own pixels (dhp +0.0039 against the
frame's +0.0036).
- MASK DEHAZE -9: dmean +0.0319, dhp -0.0013.
- FRAME CLARITY -9: dhp -0.0200 -> -0.0094, white band -0.1112 -> -0.0203, so
the frame-wide row no longer pays for its soften by flattening every white
in the frame; MASK CLARITY -9 is the same move (dhp -0.0150, white band
-0.0103) and the two now agree in direction, sign and rough magnitude at
-9. CLARITY +9 is untouched on both sides (+0.0335 mask, +0.0307 frame) and
every other knob's numbers are unchanged to within +-0.0005, which is the
run-to-run noise of the same harness.
`step` was the uniform's first name and SkSL refused the shader with it (a
builtin), which is how a whole DEHAZE row came back with all-zero deltas in the
first measurement after the change; `stepPx` is what compiles. `npm run
typecheck` and `npm run build` are clean, and the stage draws with no page error
(the only console error is the dev server's own `/api/events` 404).
Not ported: nothing. The phone's renderer has no gradient mask and no
atmospheric-light estimate to mirror; `shared/utils/toneShader.ts` and
`shared/utils/gradientMask.ts` are the web engine's own files.
Probes: measure-parity (both phases in one run, one photo, before and after —
the same harness the previous commit was scored with), measure-dehaze2 (the same
script with only DEHAZE in both phases, plus a console listener, which is how
the `step` uniform was caught), sim-dehaze-dcp (the offline simulation that
picked the min-patch over the average: clear frame +9, contrast 0.0248 -> 0.0292
against the average's 0.0248 -> 0.0235).

web: import the camera's RAW, and grade it like the phone
The studio took JPEG, PNG and HEIC and nothing else, so a photographer's own negatives never reached it. A RAW now loads the way any other file does — `isRawName` reads the extension off a 24-entry list, the file goes into OPFS under one slot (`current_image.raw`, beside `current_image.name`, so a reload finds it again) and `rawDevelop` runs it through LibRaw-wasm: half size, 16-bit output, camera white balance and the camera's own 3x3 matrix, in bands of 2M pixels so a 30MB file never holds a second copy of itself. `example-sony.ARW` (30.3MB) lands as a 3120x2084 picture, no page error. DEHAZE joins the FX tab, where Lightroom keeps it: a chip off the same PARAM_DEFS entry (`dehaze`, 0..10) so nothing new renders chips, and the pass is the dark channel prior — `atmosphericLight` reads A off a 32x32 draw of the photo, `DEHAZE_SKSL` takes omega up to 0.95 over a floor of 0.1 — measured at 71.8% of the stage's pixels moved between 0 and 10. The gradient mask grows the six knobs the phone's has: HIGHLIGHT, SHADOW, WHITE, BLACK, CLARITY and DEHAZE. The mask's falloff is a smoothstep rather than a line, and CLARITY/DEHAZE inside a mask get a blurred copy of the photo plus the air A as a second child of the mask shader — so a mask's clarity is clarity and not a flat brightness lift. The column shows all nine rulers; CLARITY 9 moves 42.2% of the stage, DEHAZE 9 moves 27.9%. CLARITY stops reading the whole photo per pixel: the single pass that sampled a 15x15 box 225 times is now the three passes the same math wants — 1x15, then 15x1, then a blend, `orig + (orig - B) * 3.2` — about 30 reads. Both signs work (77.4% of the stage moves at +10, 79.6% at -10), and the negative branch keeps its mist as it was. The pointer reviews a look before it is taken: resting on a PHOTO STYLE chip or a recipe chip lays that look on the photo while it stays there and gives it back the moment it leaves — byte-identical, measured on four of them (24.9%, 23.8%, 24.5%, 25.3% of the stage moves on, 0.00% off) — while the recipe, the UNDO stack and the session stay on the look the click left. A hovered look brings its colour alone: the masks, the dust spots and the mosaic of the photo being edited ride along, or a pointer crossing a chip row would rub them off. A PRO sim is left out, since a hover that showed its look would hand over what the click gates. Probes: e2e-raw-verify, e2e-dehaze-mask, e2e-mask-verify, e2e-clarity-verify, e2e-hover-preview2. |

web: make EXPOSURE, EV and HIGHLIGHT mean what Lightroom means
A stop is a multiplier on light, so EXPOSURE and EV stop living in the sRGB colour matrix and get a linear-light pass of their own (EXPOSURE_SKSL: linearise, `C * 2^EV`, re-encode). The matrix keeps CONTRAST: a gain on encoded values is what made +1 EV land at x1.5 instead of x2. Measured on the neutral PROVIA sim: EV +1 = x2.011, EV +2 = x3.999, still unclipped at 239. The pass sits between the matrix and the tone shader, and the tone / cinema / curve / glow / halation children all sample through it, so HIGHLIGHT finally sees the value exposure produced instead of the one before it. Recovery keeps `L + strength * mask * (1 - L)` over `smoothstep(0.50,1.00,luma)`, and the colour comes back as `color * (luma_new / luma)`: a blown white stays white (255 -> 255 at -10, 255 at +10), a 0.8 grey loses 33 luma, the midtones beside it do not move. AUTO is the histogram the LIGHT tab already draws: weighted mean luminance (guard 0.001), target 0.48, `log2(0.48 / avg)` clamped to +-2.5 EV, handed to the same knob. A 0.251 grey asks for EV 0.9 and lands at mean 83.0 against the 83.3 predicted, idempotent on a second press. A stock's own bias rides the same pass (`SIM_EXPOSURE_BIAS_EV`, VIVID +0.25 EV) and cancels against the knob, so -1 EXPOSURE on VIVID returns the CLASSIC rendering (measured 0.4149 vs 0.4177). ponytail: the phone app's `src/utils/colorUtils.ts` keeps the old math, so the two copies have to move together; recipes saved before this commit (EXPOSURE 2, HIGHLIGHT +-1) render under the new stop semantics. Verified on the rebuilt container (BASE=http://localhost:8090): - web-exposure-probe.cjs 20 PASS / 0 FAIL (neutral 128 -> 128, EV +1 ratio 2.011, EV +2 ratio 3.999, EXPOSURE +10 ratio 5.62 / -10 ratio 0.172, AUTO EV 0.9, HIGHLIGHT -10 on a 204 grey 204 -> 171, white 255 -> 255, no console errors) - sim-exposure-test.cjs 9 PASS / 0 FAIL (classic 0.4149, vivid 0.4531, knob -1 returning 0.4177, bias 0.0382) - regression suite, 28 probes: mask 53/0, brush-edit 35/0, heal-idle 23/0, heal-zoom-drag 28/0, sims 31/0, sim-vivid 9/0, white-black 4/0, temp-swatch 33/0, tone-curve clean, compare 25/0, create 52/0, wb-preset 33/0, zoom 25/0, save-recent 25/0, web-smoke 9/0 (its export step was stale — EXPORT opens a size picker now). panel-test 4 FAIL, histogram-wb 1 FAIL, studio-save-hl and progate timeouts, landing-test 6 FAIL ($0.99 pricing) are pre-existing. - npx tsc --noEmit clean. |

web: add the B&W HIGH CONTRAST film sim to the PRESETS rail
The chip lands after ACRIPES and is a mono stock of its own, so it gets its own
baseFilter ('mono-high-contrast') rather than borrowing Acros': the PHOTO STYLE
chips are keyed by baseFilter, and the two greys must sit side by side.
The look is the B&W MIX plus a push at both ends. The mix rides the matrix — a
non-BT.709 row set (0.38/0.56/0.06, identical rows, sum 1.00) so a red roof
reads bright, a blue sky deep, and the separation is contrast before any curve.
The push rides FILM_TONE (shadow -0.32, highlight +0.26) so the ends move
without touching the midtones, and the midtone slope is SIM_CONTRAST_BIAS (4
contrast units) next to the sim's own exposure bias. The knobs stay at neutral:
a sim is colour and tone only.
Both B&W stocks being mono is now asked once, through isMonochromeBase, so the
colour-only stages (saturation, white balance, R/B fine-tune, chrome, hue
mixer) and the MONO strip label can never half-apply to one of them.

web: the three mixer knobs move the whole image, a frame chip toggles itself, ROTATE lets go when STRAIGHTEN steers
HUE, SAT and LUM leave the colour row: behind an IMAGE divider they are hslHue/hslSat/hslLum, seeded into the shader's band accumulator at full weight for every hue, while the eight band chips keep picking which colour the panel on the photo edits. The image lightness term stays ungated so a frame drained to grey by -SAT still answers +LUM. FRAME loses its NO FRAME chip: pressing the frame already on the photo takes it off. ROTATE's quarter turns stop lighting the moment the fine angle leaves 0, so the strip shows which of the two is steering the photo. |

web: add CLASSIC VIVIDIPES, spliced at the blue row
Classic Chrome's blue row, verbatim, with the red and green rows taken from VELVIPES: skies keep the muted teal/cyan lean while everything that is not blue reads loud. The shadow crush rides along from FILM_TONE, since it belongs to the stock rather than to a row. CLASSIC CHRIPES stays untouched beside it. |

web: move WHITE/BLACK onto the WB tab as per-channel points
LIGHT already spends its slope budget on the tone knees, so the two end points were doing nothing a tone knob could not. On WB they act on each channel's own distance from the end: the darker channel of a shadow and the brighter channel of a highlight move most, which neutralises a cast at the toe and the shoulder. Both shuffles stay cubic in the channel value, so every channel's curve is still monotonic (>= 0.46). |

web: fold the create form's groups and add the white/black point rows
The CREATE RECIPES form had grown into one long scroll. The six categorical groups (SIMULATION, DYNAMIC RANGE, GRAIN EFFECT, COLOR CHROME EFFECT, COLOR CHROME EFFECT BLUE, WHITE BALANCE) are now native <details> folds — the browser keeps the open flag, so no state and no library. The two tone-curve ENDS join the numeric grid: EXPOSURE (the matrix gain the IQ tab already drives), EV (the old EXPOSURE COMP. row, renamed to the phone's word), WHITE and BLACK. WHITE/BLACK are new ColorAdjustments fields, applied in TONE_SKSL as cubic end-weights rather than another smoothstep knee — the HL/SH knees already spend the slope budget, and the cubic keeps the curve monotonic for every combination (derivative >= 0.46), so a brighter input can still never come out darker. Both are optional, so stored recipes keep working. |

feat(panel): cascading columns, WB colour swatches, stronger HDF glow
Layout - the panel is a cascade of columns: the rail's tabs, the tab's chips, the open chip's sub-chips, then the ruler. A child column no longer hides the column it came from (TEMP -> COLOR TEMP keeps TEMP visible); chips stack one per row instead of wrapping - FRAME's WATERMARK opens its own column, so the frame chips stay put - CREATE RECIPES gets the wide column its two-up form needs WB colour swatches - the ruler draws a colour box under the slider that follows the value: COLOR TEMP is the Kelvin colour (Tanner Helland), TINT runs green -10 -> neutral 0 -> magenta +10 HDF EFFECT - knee 0.55..0.85 -> 0.45..0.75, blur 0.004+0.015n -> 0.006+0.024n of the width, screen alpha 0.15+0.35n -> 0.28+0.52n: a wide halo on the highlights instead of a hairline glow. Web copy of toneShader only — the phone keeps its own tuning. Tabs - rail order is PRESETS, FAVORITED, WB, LIGHT, FX, FRAME, CREATE RECIPES |

Add self-contained docker/ stack for the web UI
`docker/` now holds the whole web build — frontend (Vite + React + CanvasKit),
backend (Fastify + SQLite) and the compose file — so the folder can be moved to
another machine and run without the React Native project:
cd docker && cp .env.example .env && docker compose up -d --build
Only `${WEB_PORT:-8090}` is published; nginx serves the SPA and proxies /api to
the `api` container over Docker's DNS. Photos never reach the server.
The shared render code is vendored into `docker/frontend/shared/` and aliased to
a CanvasKit shim, so the app's own frameUtils/toneShader/jpegDpi run unchanged.
Fix the all-black render on GPU surfaces: `MakeWebGLCanvasSurface` creates a
separate WebGL context per call, and a texture from one context cannot be
sampled by a surface on another — so any pass that drew a snapshot onto a second
surface (output sharpen, screen sharpen, polaroid/wallframe cards) came out
solid black, while the raster fallback was correct. Use one shared
GrDirectContext + MakeRenderTarget instead.
Verified in headless Chromium against the running stack: 12MP JPEG in, preview
mean=120.5 sd=60.5, export 2048x1536 mean=107.2 sd=62.1, JFIF density 300/300,
EXIF present, no console errors; health/signup/login/me/recipes all 2xx through
the nginx proxy.
